REDUCTIVE CLEAVAGE OF AXIALLY DISYMMETRIC TERTIARY AMINES AND QUATERNARY AMMONIUM SALTS BY LITHIUM ALUMINIUM HYDRIDE. SYNTHESIS OF NEW 1,1'-BINAPHTHYL SUBSTITUTED AMINES

Article abstract of DOI:10.1016/S0040-4039(00)61900-7

Axially disymmetric tertiary amines or quaternary ammonium salts A are synthesized by double alkylation of primary or secundary amines with racemic or optically pure 2,2'-bis(bromomethyl)-1,1'-binaphthyl.Their reductive cleavage by lithium aluminium hydri
